Question

For what value of k will the following pair of linear equation have no solution?
2x + 3y = 9
6x + (k-2)y = (3k-2)​

Answer 1

Answer:

k=7

Step-by-step explanation:

To get the following pair of Linear equations no solution the comparison of ratios will be a1/a2=b1/b2 is not equal to c1/c2

Therefore 2/6 = 3/[k-2]

2×[k-2] = 6×3

2k-4 = 18

2k =18-4

2k =14

k =7
